I can’t remember the last time I saw a bubble in a poured silicone mold… but then, I am a moldmaker and I have a vacuum pump.
You CAN use this to produce printed molds- but the resin costs 8 times as much as tin cured silicones.
The the cost of one liter- I can buy 2 gallons of silicone.
I advise using the form 2 to print a CASING that accurately maintains a 3/16" gap between your master and the inner wall of the casing… ( no counting undercut areas where the rubber will be thicker for draft ) and then Pouring silicone into the gap.
